Enterprise Firewall & VPN Solutions

Secure your network perimeter and enable safe remote access with advanced open-source and commercial firewall appliances.

Overview

In an era of relentless automated cyber attacks, ransomware, and remote workforces, a basic ISP router is entirely insufficient to protect your business. Your network requires a hardened perimeter capable of deep packet inspection, intrusion detection, and secure encrypted tunneling. S-Tech InfraCare designs and deploys robust firewall architectures that serve as the impenetrable front door to your digital assets.

We heavily advocate for powerful open-source firewall platforms like pfSense and OPNsense, which deliver enterprise-grade security features—such as high-availability clustering and advanced traffic shaping—without the crippling recurring licensing fees associated with commercial vendors. For organizations with specific compliance requirements, we also expertly deploy and manage commercial firewalls from Sophos, Fortinet, and Cisco.

Beyond the perimeter, we architect highly secure Virtual Private Networks (VPNs) utilizing modern protocols like WireGuard and IPsec, ensuring your remote employees and branch offices can access corporate resources seamlessly and securely.

Our Solution

S-Tech InfraCare replaces vulnerable consumer-grade routers with dedicated, hardened firewall appliances. We conduct a thorough audit of your required inbound and outbound traffic, implementing a strict 'default-deny' policy where only explicitly required traffic is permitted.

We deploy advanced Intrusion Detection and Prevention Systems (IDS/IPS) using Suricata or Snort to actively monitor and block malicious traffic signatures in real-time. We also configure robust network segmentation (VLAN routing), ensuring that even if a guest device is compromised, it cannot access your secure corporate servers.

To support modern remote work, we implement secure client-to-site VPNs using WireGuard for high-speed, modern encryption, or OpenVPN for maximum compatibility. For businesses with multiple locations, we establish unbreakable Site-to-Site IPsec tunnels, creating a single, unified, and secure corporate network.

Business Challenges We Solve

Ransomware and Intrusions

Unsecured perimeters and open ports allow automated scanners to breach networks, deploy ransomware, and exfiltrate sensitive data.

Insecure Remote Access

Legacy remote desktop (RDP) exposed directly to the internet is the leading cause of network breaches for small and medium businesses.

High Licensing Costs

Commercial firewalls often require expensive annual subscriptions for basic features like VPN routing and firmware updates.

Lack of Visibility

Without deep packet inspection and detailed logging, businesses have no idea who is accessing their network or what data is leaving it.

Methodology

Implementation Process

Our structured approach ensures smooth deployment with zero business disruption.

1

Security Audit

We review your current network edge, document required open ports, and identify immediate security vulnerabilities.

2

Appliance Sizing

Based on your internet bandwidth and required features (like IDS/IPS), we select the appropriate hardware appliance.

3

Configuration & Hardening

We pre-configure the firewall in our lab, setting up VLANs, NAT rules, VPN certificates, and traffic shaping policies.

4

Cutover Deployment

Seamless installation of the new firewall during a maintenance window, ensuring minimal disruption to internet connectivity.

5

Monitoring & Tuning

Ongoing monitoring of firewall logs, adjusting IPS rules to prevent false positives, and managing firmware updates.
